lnaccordane with E' 1 principal. object ofthe invention, a Arrljttterial Carlier is provided Yincluding means Jforthe relative adjustment of `the upper andthe :lower-rods to the particular rod distancereqnired as determinedfny the reel length of .the skeins o fvyarn used Iand bythe extent of shrinkage .of the material in the wet treatment.

The mea-ns mentionedare intended @to makeit possible to determine the .changes of therod distances by 4means Q.f QdiCaftOl' .SleS when the material carrier is Vinside as well asputside of the wvat.A In thismanner the synthetic yarnis protected 4to a `CQnSideraisle `extent during Athe dyeing process and netting and feltng is prevented. For dyeing normal .material in which no considerable shrinkage takes place during the wet treatment, a predetermined yarn distance can beset eyen'before ystocking or loading the material ,a ier, pritis 1possible to adjust for a dis tancecorresponding to the reel length, in which connection the skeins may-have a ,small sas- F .dyeing lof synthetic materialin skein'formg which sst-1st he. subie/ated. te wettingY Qrshrinkins process before the actual dyeing, -the procedure is -Such that. n orderto determine the required rod .distance a .shrinkage fest iS l ,de onafsngle skein .or yarn. This reveals the egategitent ot shrinkage of the, material. The complete leading 9g the `material carrier 'with the textile lmaterial t A n earried out while taking into consideration the ya es of the degree of shrinkage which has been deterrained during vthe shrinkage restz Y The 4wettingfor shrinkage treatment maybe carried out only `ina calm, boiling bath. The material with the material carrier must, Aunder no circumstances, be taken out of the hot liquor during the shrinking and the dyeing operation. -This requires that the rod distance must be set with reference to the results o'f the shrinkage test and that the tentative setting must 'be made before the material carrier is loaded. Any subsequent adjustments of the rod distance which might become necessary can then Vbepmade during the course ,of the Wet treatment of the material on .the .loaded material carrier Awhich has `been placedin'to the vat. The design of thematerial carrier in accordance with the 'invention .provides for making adjustments or corrections of the exact rod distance-iin a ve'ryjsimple .manner 'for effecting the undisturbed execution of the shrinkage andthe subsequent dyeing process.

In accordance with a 'further object -of the invention the material carrier -is of particular and advantageous '.CDlStruCtiOn. .Adjusting means .for the upper rods 'include threaded adjusting spindles which are disposed vertically valong tparallel oppositely jdisposedpwalls of the material carrier and are Vrotatable'in synchronism fromfthe top of. the carrier "by means of a crank drive. They are disposed to cooperate with Wide carrier' or supporting sections vprovidedwith supporting yokesfor 'theyarn rods to reoeivejthe'yarn and on being rotated to adjust the height thereof. I The adjusting means vfor the flower jgroup of rods comprise simple support bars or sections with 'supporting yokes to receive the rods and threaded pins-for securing the sections in place in corresponding holes disposed at dierent 'heights v,along the oppositely disposed Walls. Y

VIn*accordance with the invention` a scale can 'be provided for setting the required height ofithe upperrods along each side Waljl of the openfront of the carrier. The upper edge ofthe adjustable supporting bars serves ast'ne indicator. A further indicating scale to show the height of the upper rods can be Yprovided inthe head of therrnaterial carrier. @By means vof this scale the distanceV of the upperirods from thevlower rods can be corrected after the material carrier is disposed in the vat.

` For the purpose of securingthe rods against sliding out ot their yokes when the carrier has been loaded and when the direction of ow of the `liquor is changed so that the liquor flows from the bottom to the top, it is .necessary toY lock the rods by means of transverse locking rods, which is accomplished in a simple and safe mannerpby sliding the locking rods into lugs which are provided in the walls ofthe carrier.

The material carrier is provided around the upper Athird. of its space kwith a horizontally disposed perforated spacing plate which serves for distributing the liquor and onto the ends of which cover plates can be hung at the open sides of the material carrier for the protection vof the foremost rows of yarn, which plates may be .locked into place along the vertical side sections of the material carrier by latching means of any known type, using a key of polygonal cross section.

In accordance with a further `object of the invention the oppositely dispo-sed side Walls of the material carrier are inwardly odset along the lower third part thereof and provided in that area with the adjustable kcarrier bars or sections which st'tpportl the yokesfor the lower rods. 'Along the upper portion of these walls .in the area corre-V sponding to the offset part the threaded adjusting spindles are located; Threaded sleeves are provid'edby meansyof which the carrier bars or sections for the upper rods are secured` to the threaded spindles in a manner that the spindles upon being rotated carry these bars upwardly or downwardly, depending on the `direction of rotation.

Other objects and advantages of the invention will become apparent from the following specication withgrefer ence to the accompanying drawing which illustrates a 3 material carrier in accordance in which:

Fig. 9 illustrates in a sectional view similar to Fig. 3 a vat including the Ydye lluid or liquor circulating assembly with a material carrier placed therein, and

Fig. 10 is a plan view of the apparatus in accordance with Fig. 9.

The material carrier which is a frame-like structure of generally rectangular cross-section is constituted essentially of two side walls 1 which are disposed parallel and opposite to one another and which are connected with one another at their lower ends by two oppositely disposed transverse struts 2. One of the transverse struts is suitably removably connected with the side walls to permit supplying the material carrier more conveniently with the fiber material which is to be treated and which is indicated in Figs. 2 and 3 as being in the form of suspended skeins of yarn. Approximately in the upper third between walls 1 and 2 a perforated sheet of metal 3 is mounted for the distribution of the iluid or liquor. When the material carrier is placed into the vat a (see Fig. 9) this sheet is located at the height of'an intermediate overflow wall b of the vat. Walls 1 are connected at their upper ends with transverse members and a cover plate 4. At the lower third of their area walls 1 are offset inwardly toward each other at 1. The offset location 1 provides space for mounting bearings. Below the perforated metal sheet 3 in the upper part of the material carrier, a yarn rod carrying bar 5 is located on each side 1, which bars are adjustable in height and which are connected with vertical threaded adjusting spindles 6, journalled at the bottom in bearings provided on the oiset portions of the side walls for adjusting the height by rotating the spindles simultaneously. The yarn rod car rier bars 5 are each provided with two rows of yarn rod yokes 7 disposed in two rows above one another and which are provided to receive the upper horizontal bars 8 for suspending the skeins of yarn and which are disposed in staggered relation to each other. are formed in the manner indicated in Figs. 5 and 6. They are hollow rods which, as seen in Fig. 5, are of somewhat reduced diameter at their ends and which in this location define a closed shell formed by a welded seam 8. Fig. 6 shows a section through the yarn rod 8 at any position intermediate its two ends. The edges of the yarn rod are turned over or beaded along one side with the invention and The yarn rodsv in a manner that between the beads a slot 8" is formed which extends longitudinally of the yarn rod. A Series of ow-oif apertures is provided in the shell along the side oppo-site the slot.

In the lower third of the walls 1, i.e. below the offset locations 1', there is located between walls =1 a further support bar for the yarn rod yokes 9 which in a manner analogous to that shown at 7 are arranged in two rows, one above the other, and staggered with respect to one another and receive the lower yarn rods 10. This Support with the yokes 9 is adjustable in height and is provided with threaded setting pins or set screws (not shown). It is possible by means of the latter to connect the support at the different heights with the walls 1.

y The adjusting spindles 6 which are journallecl proximate Ymaterial against damage and smudging.

their upper ends closely below the metal cover 4 are provided in pairs on each wall 1 at equal distances from one another and support each at their end above the cover plate 4, through which they extend, a bevel -gear 13 which :reshes with corresponding bevel gears mounted on shafts 12 provided with cranks 11. The synchronous operation of the crank shafts 12 and thus of the spindles 6 i-s insured by means of a chain drive 12. By turning the crank shafts 12 the spindles 6 are rotated, and depending upon 'the direction of rotation the threaded guide sleeves 14 are adjusted upwardly or downwardly together with the yarn rod support bars 5 to which they are securely fastened against axial displacement, and movement causes increase or decrease in the distance between rods 8 and 1t). One of the yarn rod support bars 5 may be used t'o serve as an indicator for the adjusted position of the support bars 5 in a manner that the location of the indicator means can be read on a scale 15 provided on the side wall 1.

Supporting lugs 17 are provided on support bars 5 into which locking rods 16 may be inserted in a manner that the yarn rods 10 are frmly positioned upon loading the material carrier.

Cover plates 18 are provided along the open sides of the material carrier which, after the loading, protect the In order to make it possible to remove the plates readily, they are mounted by means of pins 19 in bores along the edge of perforated intermediate bottom 3 and secured, for example, by means of conventional latches 20.

An indicating device 2,1is suitably coupled with one of the crank shafts 12 which is provided with athreaded portion, the indicator position of which can be read on a scale (see Figs. 7 and 8). The indicator is guided in a longitudinal slot of the scale support and in this manner is prevented from rotating so that it moves along .the scale when shaft 12 is rotated. As indicated in Fig.

8, the threaded portion on shaft 12 is covered by a protector shield. This arrangement makes it possible to determine from above the particular adjusted distance between rods 8 and 10 from one another in the material carrier which has been placed into the tank o r vat and to correct any inaccurate setting which is noted before the dyeing operation. In this manner an opportunity is provided, if after shrinking of the material the required sag needs adjustment, to lengthen or shorten the skeins of yarn as may be required for carrying out the'dyeing operation, i.e. to compensate for or correct any difference which results from the shrinking process.

A device 22 is provided for hanging the material carrier into the vat a or for removing it therefrom. At the head of the material carrier, rails 23 are provided which present at their free ends recesses for engagementby securing members on the Vat a (not illustrated), by means of which the material carrier is fastened in the vat.

lt is not absolutely necessary to provide at the upper end carrier 5 and the lower rod carrier several rows of rods at different heights because it is possible at any rate to adjust to each reel length between about 1640' and 2790.

`Instead of providing two threaded adjusting spindles 6 along each side wall 1 with two cranks 12 at the head, it is possible for small capacity requirements to provide only a single spindle along each wall together with a crank, in which case additional provisions must be made, however, to prevent the rod carriers 5 from becoming wedged in or bent during their movement.

The lower yarn bar yokes 9 could also be mounted permanently on the walls 1 instead of being adjustable, in which event additional rows would have to be provided. The essential point is that a relative adjustment is possible between the upper and the lower rows of rods.

The skein material to be dyed or subjected to any other wet treatment is supplied onto the yarn rods in the manner Vindicated after they have been set for -the rethe.;t trademark Orlon, greater .annesse quired yarn a distancedepending on..the working.0pe1 .tion`nd'on .the reel Llengtlif With normLmaterilgtO be Adyed without a` shrinking proc.ess,'it}is possibleito i.d0 this in that-the .dist'anceof.tleupper-dge oflitheupper yarn rod to the lower edge of the lower `yarn rod is adjusted by .approximately` adlaniwidthilessitlanithe clear reel length ofthe yarn material toheldyed.

For this reason the operation with the last mentioned combined shrinking and dyeing process involves only the lower yarn rods mounted in the higher positions. Y

The vat a which is not a part of the subject of the application is provided with a liquid intake c and a liquid drain d. A motor at e moves a propeller in a manner that the treatment liquor takes the course indicated between arrows in Fig. 9. A heating assembly f is mounted in the path of the liquor ahead of the overow b which may be supplied with steam through a supply stub g andan outlet stub h.
